I know that the checkmark is used if a topic is answered as desired, but what icon should I choose if, say, some days have gone by without any answers to the question initially asked and I want to close the topic do to lack af activity?

A (very) short explanation of the icons would be nice.

Thank you!

P.S. If this is explained somewhere, please let me know ... and sorry for asking this question.

I must confess I don't know either. And to be honest: I don't really care. The only icon important to me is the “solved” icon which I would only use if a question really is solved. If it isn't I would leave the question unsolved regardless of the activity of the topic.
